“…In experiments based on similar approach Rana et al (2012) reported an increase in Fe and Zn content of wheat shoots and Shabayev (2012) has reported an increase of around 30% in Fe and 41% in Zn in wheat in response to PGPR treatment; we have also reported an increase in the root and shoot Fe content in rice in response to PGPR treatment (Sharma et al, 2013).…”

Plant growth promoting rhizobacteria (PGPRs) improve growth of the host plants in a variety of ways. For this reason five bacterial strains isolated form the rice rhizospheric soil (B 15, B 17, B 19, BN 17 and BN 30) and three standard PGPR strains (viz. Pseudomonas putida, Pseudomonas fluorescens and Azospirillum lipoferum) were tested for plant growth promotion when applied to the rice plants as seedling treatments. The experiment was conducted for two rainy seasons of the years 2010 and 2011. Rice plants inoculated with the bacterial isolates recorded an improved plant growth and higher photosynthetic capacity signified by the higher chlorophyll content. Root and shoot dry mass was also found to be increased in the inoculated plants. Besides these iron and zinc content of the treated rice plants was also found to be higher in comparison with the uninoculated control plants. Hence, it can be concluded that application of PGPR has immense potential to be used as agricultural crop inoculants as they promote plant growth as well as improve the health and yield of the plants.

“…La importancia de conocer la composición química estriba en la calidad del material vegetal de las plántulas, y la reserva de nutrientes minerales, altas concentraciones de nitrógeno y potasio pueden influir sobre el crecimiento y la supervivencia de las plántulas (Villar et al, 2004).

“…Sin embargo, cuando solamente se aplica solución Steiner eliminando todos los microrganismos solo se beneficia la concentración nutrimental e influye en los índices de crecimiento debido a que la nutrición aplicada a las plantas puede afectar la estructura de las comunidades bacterianas en la rizosfera (Glick, 2012, Shabayev, 2012. Y es que el proceso de colonización en un paso decisivo en la interacción entre bacteria y planta, esta última secreta exudados ricos en nutrimentos que son utilizados por las bacterias en la sprimeras etapas de reconocimiento (Abaid-Ullah et al, 2015).…”

La producción de plántulas de calidad es primordial para que durante el trasplante se propicie un crecimiento óptimo y buenos rendimientos del cultivo; por ello, el objetivo de la presente investigación fue determinar el efecto de bacterias promotoras de crecimiento vegetal y el manejo de la nutrición en la fisiología y crecimiento de plántulas de chile serrano. En condiciones de invernadero se llevó a cabo un experimento, con chile serrano var. Tampiqueña 74, bajo un diseño completamente al azar con arreglo factorial de 2×2×2. Los factores fueron: inoculación (con o sin Pseudomonas tolaasii), sustrato (con y sin esterilizar), y solución nutritiva (Steiner y té de vermicompost) con un total de ocho tratamientos con cuatro repeticiones cada uno. Los resultados indican que el efecto de P. tolaasii es altamente significativo en sustrato no esterilizado y con solución Steiner, donde las plántulas presentaron mayor altura, diámetro del tallo, área foliar, y la biomasa seca de parte aérea. Además, aumentó la concentración de NO3 en savia. Con el té de vermicompost la inoculación solo impactó en la longitud y volumen radical; mientras que con la solución Steiner únicamente tuvo efecto en el contenido nutritivo de N y K+ e índices de crecimiento. La inoculación de P. tolaasii en plántulas de chile serrano favorece la fisiología y concentración nutritiva siempre y cuando no se esterilice el sustrato. El menor efecto sobre las plántulas ocurre si sólo se suministra té de vermicompost.

“…They affect plant nutrition, growth and yield through several mechanisms including: (1) solubilization of sparingly soluble minerals, (2) nitrogen fixation, (3) decomposition of organic matter, (4) production of siderophores, phytohormones, vitamins and enzymes and (5) increase efficiency of root system in nutrient uptake (Glick et al, 1995;Lucy et al 2004;Rosas et al, 2008;Altomare and Tringovska, 2011). Several published studies under greenhouse and field conditions proved the importance of PGPR in increasing growth and yield of field crops (Ozturk et al 2003;Abd El-Azeem et al 2008;Zorita and Conigia, 2009;Zabihi et al 2011;Shabayev, 2012). Among the most used PGPR are bacteria belonging to the genera Azospirillum and Micrococcus.…”

Effect of seed inoculation with the rhizobacteria Azospirillum brasilense AC1 and Micrococcus roseus SW1 in combination with P fertilization at levels of 0, 50 and 100% of the recommended dose on yield and nutrient contents of wheat plants grown on a sandy soil was studied in a greenhouse pot experiment. The results showed that grain, straw and biological yields of wheat were significantly improved with raising Plevel. Also, the seed inoculation with the two bacterial strains caused significant increases in both grain and straw yields as compared to the uninoculated control. In addition, both yield parameters were significantly higher with the strain AC1 than with SW1.The highest grain and straw yields were obtained with 100% P dose plus A. brasilense at which the increments over the corresponding uninoculated control were 44.2 and 50.9%, respectively. The uptake of N, P, Fe and Mn by grains as well as the total uptake of N, Zn and Cu by plant were significantly increased at 50 and 100% P doses as compared to the control, but the differences between the two P fertilizer doses were not significant. The uptake of K by grains and straw and uptake of P, Fe, Mn and Zn by straw as well as the total uptake of P, K, Fe and Mn by plant were also significantly increased with increasing P fertilization level up to 100% dose. The uptake of all measured nutrients (N, P, K, Fe, Mn, Zn, Cu) by grains and straw were significantly increased by seed inoculation with the two tested strains relative to the uninoculated controls. The foregoing results revealed that the effectiveness of the tested strains individually for improving yield and nutrient uptake by wheat decreased with increasing the applied levels of P. The results indicated also that inoculation of wheat with the two mentioned rhizobacterial strains improved yield and nutrient contents in plant. The dosage of P mineral fertilizer currently applied for wheat in the Egyptian sandy soils might be reduced by combination of A. brasilense AC1 inoculation plus 50% of the recommended superphosphate dose. These results are recommended for field evaluation under different soils and environmental conditions before generalization of the two tested strains as biofertilizers.
